I have a blackberry bold that constantly reboots in a loop, when it is low on battery it reboots with no screen, as you charge the battery it gets further and further through the process till eventually it boots up fully stays on for 10 seconds and reboots again. Even if I start the phone and turn it off manually it eventually starts to reboot again. I have tried a software restore using apploader strangely it does not reboot as often and stays on long enough to complete 3/4 of the process when it reboots it continues to restore and appears to work ok for a while then it starts again. Someone has said it maybe water damage.

Tried the apploader software installation again, it rebooted twice during install then continued and completed successfully, then when it completed it rebootedonce then stayed on for at least 10 minutes before rebooting in a loop again the phone stays on approx. 10 secs after booting fully
